Samsung 46 in. Flat-Panel LCD HDTV Questions & Answers
Our samsung TV is taking forever to turn on. When
Check high voltage circuit on the power board. At where 120 volts AC enters, then a fuse, then small high voltage transformer, follows by a capacitor (100 uf rated at 450 volts) check voltage at the capacitor (should be 390 or above). Sumsung should not have used such a small size capacitor - too easily "short" out and become useless. Try 300 uf or 350 uf (but must rated for at least 400 volts). Difficult to buy this size capacitor without Radio Shack around. Cut some capacitors off power supplies and connect them in parallel. Good luck.
Everytime I try to change
Hello... Your TV speakers are turned off. If you don't have a sound bar or a surround sound system, go into the TV menu, audio, speaker settings and turn them on. If you have a sound bar or surround sound system, use the remote for that system to adjust the volume. I hope this helps!
I have a samsung 1080P, when I turn it on it takes
I had a similar problem with my 42 in Philips LCD HDTV.
Here was the problem. My Power Supply Board had several bad capacitors. I opened my TV (warranty was expired ofcourse) and found four bulged capacitors on the PSB. Many major electronics companies Philips/Magnavox,Sony, Panasonic, and others were sold capacitors that failed in 2-5 yearsinstead of 10-20. The capacitors failprematurely due to a lack of preservatives. Unfortunately, they were installed in allsorts of devices and cause a wide range of failure problems.
Here are some options for you.
1. Have it fixed by a professional $$$$$$$??????? (Is itunder warranty?)
2. Open your TV and find PSB. (The board that the power cordplugs into) Check for faulty caps. If you find some (bulged or leaking) bad capsreplace the entire board. The entireboard costs around $250 right now because they are in high demand right now. Theycan be found at tv-part.com but supplies are limited. I would definitely shop around though.
3. Remove and then replace individual faulty caps. This takes some soldering skill.
Caps are inexpensive and if you can take care of it yourselfit will save you hundreds.
This
may be your problem. If you determine that it might be.

It sounds like the microcontroller is getting confuse, try contacting Samsung to see if there is any firmware updated needed for your model.
When you turn 'on' the tv...the tv continuously 'clicks'
The clicking noise is caused by the relays on the power supply board trying to power up the system. Your TV has detected a problem that's causing the power supply to shutdown. Someone knowledgeable in electronics can track down the problem. The SOURCE of the problem could be another board other the power supply.

Samsung 55 TV White vertical patches?
It sounds like you might be dealing with backlight bleeding or an issue with the LED backlighting in your TV. This can sometimes occur over time due to normal wear and tear or manufacturing defects. If it started as a faint single brighter section and has now expanded to four, it's likely a hardware issue. While it may not be an easy fix, contacting the manufacturer's customer support or a professional technician would be a good next step to diagnose and possibly repair the problem. If you'd like, you can share the pictures for a more accurate assessment.

These LEDs are very susceptible to static electricity damage. What happens when they get zapped is a tiny threading fault starts in the LED crystal. The aluminum contact metal starts migrating into the crack, makes it wider and longer, and eventually goes all the way through the LED and shorts it out. When that happens, the metal overheats and burns out the LED so the entire string goes dead.
What this means for you is that the original LED may have been may have been zapped at the factory. The replacement strip likewise, or when it was removed from another TV (if it is a used part), or when you put it in. It should have been in anti-static packaging. You have to be very careful not to touch any of the circuitry on the LED strip, and make sure you ground your hand to the TV metal both before picking up the LED strip and right before connecting the strip to the TV. Better yet, use an anti-static wristband connected to the TV frame.
It is possible that the LED driver for that string is pushing too much current, but that's not likely. You would probably notice that part of the screen is unnaturally bright.
